The oldest computer Michael ever programmed was the Burroughs 220. It was the last commercial vacuum tube computer, running at a blazing 5,000 instructions per second, with 5,000 eleven-digit words of memory!
Many have probably seen it on TV, as Batman's "Crime Computer”. ;-) Yet, it could do wonderful things, like run Algol 58 and support interactive graphics. It was a "personal computer" to Michael, and he was delighted to find that he could simulate it (at about half its native
speed) on an Apple II. Join him in this session to share the joys of recreating a classic digital computer.
